Figure 5.

Degree of fluorescence polarization (P) of the fluorescent probe DPH in thylakoid membranes from Ailsa Craig (A) and tangerine (B) plants, treated with low light (LL) at control (NT) or low (LT) temperature and after recovery at optimal conditions. Mean values ± SE were calculated from two independent experiments with at least 3 parallel samples at every time point (n = 6). Significant differences between values at p < 0.05 were estimated by Fisher’s LSD test of multifactor ANOVA analysis and indicated with different letters.
